Samsung starts mass production of 30.72TB SAS SSDs

Samsung unveils the world's largest solid state drive on Tuesday which boasts a whopping 30.72 terabyte (TB) storage space. On the inside one can find Samsung's latest V-NAND technology with 64-layer, 3-bit 512Gb chips.

Samsung announced the production of the PM1643, a 30.72TB SSD. In addition to the new capacity, the latest enterprise SSD by Samsung is touted to deliver almost twice the performance levels of the previous generation.

The PM1643, as it's called, is built from 32 sticks of 1TB NAND flash packages, each of which contains 16 layers of 512Gb V-NAND chips.

It's no slouch in performance, with a read speed of 2100MB/s and a write speed of 1700MB/s - which is a madman compared to current domestic offerings. Using a 12Gb/s SAS interface, the PM1643 is quoted to deliver random read and write speeds of up to 400,000 IOPS and 50,000 IOPS, and sequential read and write speeds of up to 2,100MB/s and 1,700MB/s, respectively. This is three times faster than a normal SATA SSD. As Samsung executive VP of memory sales Jaesoo Han said in a press statement, the company will "continue to move aggressively in meeting the shifting demand toward SSDs over 10TB". To make the most of the other components Samsung introduced a new highly efficient controller architecture that integrates nine controllers from the previous high-capacity SSD lineup into a single package. The new drive also incorporates the TSV (Through Silicon Via) technology that interconnects 8Gb DDR4 chips creating up to 10 units of 4GB TSV DRAM units, with a total of 40GB of DRAM. It also provides support for metadata protection and data retention and recovery after a sudden power failure.

Talking about the software, the SSD features an error correction code (ECC) algorithm that ensures high reliability with minimal storage maintenance. The mean time between failures is 2 million hours. On the durability side, Samsung says you can write 30.72TB of data  thats the whole drive  each day for five years. The prime target for these versions includes various market segments such as the government, financial services, healthcare, education, oil and gas, pharmaceutical, social media, business services, retail, and communications sectors.
